and n are rawin mounted. This directing member 8 is prefl will drop therefrom and be conveyed through erahly positioned between the hood'o and the receptacle 1 so that the same rests upon the upper edgesof said receptacle, and thus when the oil burns in the receptacle and considerable sootv collects upon the outer surface of said hood, said soot may he readily conveyed to the l'iurniiig oil within the receptacle through the medium of this outwardly inclined directing or funnel member. As this sootis conveyed into the burning oil in the receptacle, the same will cause great smoke to flow therefrom and thus, aid considerably in theheating of the sur rounding air.

In Fig. 5, I have shown a slightly modified form of device wherein a receptacle l0 tormed in the exact manner said receptacle 1, is provided with the guide rods 11,

upon which is slidahly and adjustahlf mounted the hood member 12 and also slidaloly mounted on said guide rods and resting on the upper edges of said receptacle,

is the directing inei'uber 13. [he iormiiig' and positioning of this receptacle, guide rods, hood and flange is substantially the same as in the form heretofore descrihed,

but in this instance, an additional member 1 L is provided which is substantially the same as the directing members 1.3, and 8, said member 14, however, being mounted on the guide rods above the hood 12 and having the lower edges thereof resting on the upper edges of said hood. This additional member 14, therefore,- forms a continuation or extension of the hood 12 and, thus, will cause the heat to spread to a greater area than is possible without the we of the same. I

In practice, the receptacle 1 is filled with oil or other hydro-carbons and the member 5 adjusted on the guide rods so that the lower or 'aprrcd end, or substantial apex thereof, extends within. the hydroarhon in said receptacle. ()l course, th amount that the lower end oi said receptacle. estcnds within the oil, is optional and determined by the operator and when adjusted to the desired p sition, the clamping members (3 a1 is tdi'ectively engaged with the rods 3 to retaiii said hood or radiator 5 in its adjusted position. The hvdro-cai-hnn then. ignited and it will he seen that. it the lower end of the irreu'ilicr 5 extended within said hydio carbon to an} extent. whatsoever, the flame will be extended ahout the sides ot said niein ier and causal to tlarc coincid nt with the inclination of said sides, and the heat radiating from this flame, will, oi -our.--,e be spread over a greater area than ii no such deflector vrcre provided. .-.s the oil continues to horn in the receptacle, consider able. soot will collect on the outer surfa e of the hood or spreader 5, and atter collecting thereon'to any appreciable extent, the same entirely optional with the operator.

-the evening, it will he ,whatsoever, and in. any

the medium of the flange member 8 to the burning O1lwithin the receptacle, which will cause great smoke to rise therefrom. and,

thus, aidin the heating of the surrounding air. Of course, in the use of the additional flange member, as shown. in the modified form, the device will cause the heat to he spread to a greaterarea and the use of this As the inclination of the walls of the member 5 is greater than that of the walls of said receptacle 1, it will be seen that when said member 5 is inserted within the receptacle to any appreciable extent, only a small hui'ning surface will he provided, hut as the oil diminishes, it uill he s-ccn that a greater burning surface will he provided.

This device is an orchard heater, as previously stated, and as such devices. when used, are started at the first snap of cold in seen that when the colder periods of the night are reached, greater heat will be emitted from a device such mine, the increase in heat heii'ig gradual through the increase in the burning surface due to the varied inclination of the walls of the two members. Thus, with the use of devices such as I have provided, it will not be necessary to increase the number of heaters in an orchard during the colder periods of the year or the colder periods of a day, the same being compensated for through the ad ustahility of the improved hccd or radiator member with respect to the receptacle.

From the foregoing, it will be seen that I have provided an improved orchard heater in which the amount ofheat emitted therefrom may be automatically increased the hydro-carbon or oil therein is decreased. It will further be seen that I have provided an improved radiator or hood member, the walls of which are inclined inwardly from their upper to their l wer ends, the inclination thereof being greater than the inclination of the walls of the receptacle disposed there below.

1 have shown in the drawings and descrihcd in the specification, the receptacle and hood niei'nhcr or spreader as pyi'aii'iidal in design, but it will he readily understood that the ame may he of any desired design. instance, the hood nieuiliier' designed to correspond with the design at the receptacle. it will further be seen that I iai'c provided. means for the adiustahility of the hood uwinlier with respect to the rece ita-f-le and means for the retention of said hood in. any adjusted position. It

, will still Further he seen that this hood memher may he ()5 any desired altitude or depth, 'so that it desired. the same may he allowed to touch the bottom of me receptacle and still. allow a burning surface for the oil, or

' elements embodying the preferred form of the invention, it will be understood that the latter is capable of various modifications and changes within the scope of the appended claims.

What I claim is 1. An orchard heater, comprising a fuel receptacle, guide rods extending vertically from the sides thereof, a hood adjustablymounted on said guide rods, and a directing member inclosing said guide rods and resting on the upper edges of said receptacle.

2. An orchard heater of the class described, comprising a receptacle, a flame deflecting hood adjustably supported above the eceptacle, a directing member removably J ounted on the upper edges of said receptacle to receive matter from the Walls of 3. An orchard heater, comprising a fuel receptacle, guide rods extending vertically from the sides thereof, a flame deflecting hood adjustably supported on said guide rods, a directing member. inclosing said guide rods between the hood and receptacle and adapted to rest on the upper edges of the latter, said directing member being adapted to collect matter cast from the walls of the hood and conduct the same into said receptacle, and anextension member also inclosing said rods and adapted to rest on the upper edges of said hood.

4. An orchard heater of the class described comprising a fuel receptacle, a hood adjustably support-ed thereabove and capable of vertical movement to extend partially therewithin, and a removable extension for the; Walls'of said hood applied to the upper ends thereof.

Intestimony whereof I hereunto affix my signature in the presence of two witnesses.
